I've just been having an email conversation with Maria at A8parts who has found some complete pipes for me. They are not in good enough condition to fit to a car but are complete so useable as templates. As soon as I get them I will start looking for manufacturers to see if anyone can do anything for us.

Keep the suggestions coming, I may need to send them out to quiet a few before we get any results.

If anyone has any pictures of de-constructed pipes it would be useful, potential suppliers may need to see what's inside. If I manage to locate a second set I'll strip them myself but don't really want to do this to the only set I have.

I received the pipes from A8parts yesterday. first off can someone take a look to check if they look right. I'm sure they will be but I was expecting a pipe with a curly pig tail on one end. Is that a different, probably NLA pipe?

On a second point. Do the pictures bellow accurately represent what it is that is inside one of the hoses that makes it so difficult to replicate,

On inspection of the hoses I have it looks like one of the hoses is actually quite un-remarkable in that it is simple hydraulic hoes. The solid pipework looks like the most complex part of this but should be achievable if we can find a good hose company.

The second hose seems to be, again, un-remarkable for half of it's length. Simple hydraulic hose with a solid pipe section at either end. Ok, the solid pipe is quite lengthy and has a few bends in it but surely not impossible to replicate. The second half of that pipe on the other hand does look quite special. Do you agree, have I over simplified the other 3/4 of the two pipes.

I have sent an email to Conti Tec who it looks like originally manufactured this pipe to see if they can help at all but I won't hold my breath. These big companies are not usually that interested in dealing directly with the end user.

Yeah those are proper V8 hoses, and your assessment is spot on. The part with the liner is indeed the first part of the pressure hose and that's really the only difficult bit. The inner nozzle is in the pump end banjo, and there is a support bush holding the liner in place just where that crimp is where you cut it open. The liner stops at the bolted union and then the second half is just 10mm hose.

The return is pretty simple as you've seen - its just a hose with a union on one and and a reducer on the other. That one is pretty simple to recover.

My thoughts with the pressure hose are to cut the outer hydraulic hose off and recover both the liner and the support bush. They can be put in to a new hose but instead of having a bolted union in the corner, just terminate the liner in a standard hose joiner, or maybe a 90 degree to get round the corner. Crimp two bits of hose together at that joiner and then crimp on to the rack-end banjo.

Its just a case of finding someone with the intelligence and parts to do it.

I realize I have asked a question similar to this before but has anyone done any research as to if the complex double lined section of pipework is used on another vehicle? I am making an assumption here but as this complex section has a fitting on the end it may be that this is a standard manufactured section of the steering hose and is simply connected to other bits of hydraulic hose to make it specific to a particular vehicle. That would be the most cost effective way of manufacturing these double lined hoses, make them all the same and then add the simpler, cheaper hoses to fit individual vehicles.

It may be, and I am being really optimistic here, that we simply need to identify another vehicle with this section fitted and maybe Audi still have some stock. We could then un-bolt and discard the section that isn't suitable for our cars. The other 3/4 simpler parts of our pipes, we could get made up.

It may even be that this pipe for other vehicles is not as expensive as for ours.

I will give it a week or two to see if Cont Tec gets back to me. Meanwhile i'll trawl the net for VWAG power steering pipe images, see if I can find anything that has the same complex section fitted somewhere in its construction.

Hi,
Did any of the companies ever come back on this subject?
Thanks,
Brian

Funny you should mention that. I had cause to dismantle an S6 the other day and acquired the power steering hoses from it for further investigation. They are actually remarkably similar and could be modified to fit the D2 by extending the solid pipe which runs along the rack. The pressure hose is about £280 but TPS can't tell if its still available without ordering one which implies it may also be NLA. I've asked a friend in Germany to check if it shows as available there, and if so I might have to get one to fiddle with.

Pics later

I've found myself well and truly in this pickle too. Hence why my D2's sitting weeping PS fluid on Brian's driveway.

My parts guy at Audi confirmed today that the pipes we need are listed as obsolete and 100% unavailable. He even checked all dealerships to see if anyone had them in stock. No joy.

I'm specifically referring to these pipes 4D2422893D & 4D2422893M. I am 'fortunate' enough to have replaced the 891C pipe a couple of years back.

I happen to have a spare rack, complete with pipes, from a 1999 FL car I broke for parts a couple of years ago. The unions are badly corroded but not split. However, they don't have the looped section at the column end I believe the later racks and pipes all have. I haven't taken the pipes off my MY2000 yet but I can see the looped sections are there. And I can't see any parts diagram not showing the looped section.

I spoke to a guy today at Geyer Plant www.geyerplant.com today and he sounded very non-plussed about the whole thing and said to just bring it over and he was sure they'd be able to make the pipes up.

Couple of questions for everyone:
  • Should I give them the pipes from the earlier car or the later car? Or both?
  • How many people would be interested in a set if there was a decent discount for a group purchase?

@MikkiJayne - do you have the part number or year of that S6? Or a link to the ETKA image? I could ask my guy at Audi to see if it's available. Seems he can search for actual stock whereas TPS don't appear to be able from what you've said.

Cheers, Gregor

The looped section is only on LHD cars. The PF and FL hoses are exactly the same as your pictures so you might as well take the loose ones to your hydraulics guy.

If they can make a proper replica hoses with the liner etc then I'll take a few sets.

This is the S6 pipe overlaid on the S8 one. Its about 3" shorter where it runs parallel with the rack as the S6 hose runs inside the engine bay instead of through the wheel arch. It rusts just as badly though. Interestingly, this has a solid pipe section in the pressure hose in about the same place as the support bush in the S8 one so it may be that the liner only goes about 30cm in the S6 version. Same pump though so hopefully it should work.















Part number is 4B8422893A. It shows as available but backordered on TPS's system. That's usually pot-luck whether it turns up or simply goes NLA when you try and order it hence why I'm checking stock in Germany instead (by proxy). If its available to German dealers that means we can backorder it and it will actually turn up

If it is available, I envisage splitting the pipe where it runs along the rack, silver-soldering in some hose tails, and crimping maybe 10-15cm of hose in there to make it the right length.

Also, oddly, the S6 hose is one single part number, despite being split in the same place as the S8 hose which is two part numbers.

Just a thought, can these be ordered through Audi tradition?

I whacked in the part number above in to their search bar and it returned the same but with a different end letter...maybe itís superseded the previous versions?
